View LUN Performance Data
Check boxes adjacent to the LUNs can be used for selecting and viewing the performance of up to the 
first 5 Selected LUNs. View performance graphs for one of the first 5 LUNs on its tab, or view an 
aggregate graph from the “All” tab. 
The performance view auto-refreshes every 10 seconds and displays point-in-time MB/s and IOPS 
characteristic information. 
To View LUN performance graphs, do the following:
Step 1 Choose LUN Configuration > LUNs.
The LUN window appears.
Step 2 Do one of the following:
• Highlight a LUN from the LUNs list by mousing over it and right click.
• Choose up to 5 check boxes adjacent to a LUN name and right click.

Step 5 Do any of the following:
• To view daily performance, click the icon in the top-right-hand corner of the performance graph.
• To view weekly performance, click the calendar icon in the top-right-hand corner of the performance 
graph.
• To view details of a particular time frame by click your mouse and drag it over a lower time-line 
interval, e.g., 17:25 to 17:50. 
Initiator Groups
Initiator Groups are used to map LUNs. When a LUN is associated with a specific Initiator Group, the 
LUN is only visible to Initiators in that Group. A triangle adjacent to an Initiator Group name indicates 
that there are Initiators assigned to them and a tree structure can be expanded or collapsed on click. 
Note A LUN may be mapped to multiple Initiator Groups while an Initiator cannot be listed as a member of 
more than one Initiator Group.
